TEMPLE.

' To all whom it may concern:

Be it known that I, JESSE H. lVooDwxnD, of Nashua, in the county ofHillsboro and State of New Hampshire, have invented an Improvement inCylindrical Roller-Teinples for Looms for Veaving; and I do herebydeclare that the same is fully described and represented in thefollowing specification and the accompanying drawings, of which- Figurel, denotes a top view of a loom temple provided with my improvement.Fig. 2, is an inner end view of it. Fig. 3, is a vertical section takenlongitudinally through the toothed roller of the temple.

In temples of this nature, the roller generally revolves within a troughwhose inner end is open, or between two bars in order that the cloth inpassing under the roller shall rest on the upper edges of the trough orthose of the bars vand be deflected from a straight line or standtangentially in two directions to the under surface of the roller, thesame serving to maintain the cloth against the roller. In consequence ofthe inner end of the trough having been always open or the space betweenthebars or supporting surfaces thereof being left entirely open, thebend of the cloth has been continued to an injurious extent from thetemple and in the direction of the axis of the roller prolonged towardthe middle of the loom.

The object of my invention is to remove this curvature or bend of thecloth beyond the temple and to cause the deflection to take placeentirely within the temple, and this is accomplished by closing thelower end of the trough of the roller or extending a bar across it andwith its upper surface even with the upper or bearing edges of thetrough.

In the drawings, A, denotes the temple roller armed with teeth, spurs orpoints projecting from its periphery or surface.

B, is the arbor on which the roller is supported and revolves.

D, is the trough in which the roller is placed, such trough beingconstructed with a closed inner end as shown at a.

E, is the cap or guard of the roller, such guard serving as a protectionto the roller, as well as to prevent a person from accidental contactwith its spurs or points.

The advantages of my invention may be thus stated. The first, inimportance, is,

that it actually stretclies the cloth, while on the temple more than itdoes immediately in front of the temples. That this is true, and how itis done, will be obvious upon examination. It is a well known axiom,that no line between two points is so short as a straight one. Now inthe cylindrical roller temple, as heretofore constructed the cloth iscurvedv down when passing under the toothed roller, but in my improvedtemple in consequence of the end bar or rest of the trough, the cloth,except that part, which is actually under the roller is held up in a.plane. Thus while the cloth immediately in front of the roller lies in astraight line or plane, it becomes fastened to the teeth of the roller,and is carried down underneath each and is made as much wider for thetime it is going through the temples, as a line pass ing over the innerclosed ends of the temple trough and down under the rollers lengthwiseof the two temples of the loom, is longer than a straight line extendingon a level with the tops of the trough ends and from the edge of oneselvage to that of the other.

As the design o-f all temples is to prevent the contraction of the clothwhile it is being woven in order that it may not cause the warp to wearand break as well as injure the reed of the loom, the advantage of theabove improvement will be obvious to every practical man especially inlooms having no filling stop motion or those having a flyter reed. Onsuch looms it is necessary to set the roller temples a short distanceback from the reed or cloth making point or place in order to preventdamage to the reed or the wear and breakage of the selvage yarn. Shouldthe loom continue to run after the filling may have been exhausted fromthe shuttle (as all looms without filling stop motions are liable to do)such will give the cloth a chance to contract before it is seized by thetemple teeth, and the consequence is that the cloth will not be properlytempled or held out. My improved temple obviates this difliculty to agreat extent, if not entirely, and compensates for being set back bycarrying the cloth out wider than itfinds it, and this prevents thecontraction on the reed and the bad effects of such contraction.

In the second place, the improvement makes the temples more convenientfor getting the cloth properly adjusted in them. The cloth must beloosened in order to get it into most temples. Without my improvement,it will often be pulled out of one temple while it may be in the act ofbeing introduced into the other, whereas with my improvement no suchderangement can take p ace.

A third difficulty in cylindrical roller temples as heretoforeconstructed, and applied to certain kinds of woolen goods, is, that inconsequence of the cloth slipping off the ends of their teeth, the teethbecome worn and useless. This my improvement will remedy entirely as itforces the cloth at once to the surface of the roller, and will not a1-low it to draw across the points of the teeth.

My invention has no reference to the flat conical wheel temple such asis shown in George Drapers patent of the 28th day of October, A. D.1840, but is only applicable to the cylindrical roller or cylindertemple. There is a great difference between the two kinds of temples,for in the former, the axis of the wheel is disposed vertically when thetemple is at work, Whereas with the roller temple, the axis of theroller or cylinder is arranged horizontally, and the trough in which theroller operates is also arranged horizontally. The wheel temple has notrough, nor any device which is strictly analogous to a trough, thewheel being placed in a case or box having a recess formed through itstop, and so as to receive the cloth while itis on the wheel. It is truethat the top of the box and the side of the recess support the clothafter it leaves the wheel, but as the wheel will produce no groove orbend in the cloth extending at right angles to its selvage, as does thetroughed roller temple no device such as I have added to the trough ofthe cylindrical roller temple is needed in the wheel temple,

So, in regard to the slot or entrance passage of the case of the rollertemple, it, owing to the cloth being seized close to its selvage by thepoints of the wheel produces a positive evil as it causes the cloth tobend around and under the periphery of the wheel, and thus leaves theedge or selvage of the cloth rolled or folded over on the cloth when thelatter is taken from the loom. lVith my improved roller temple, theclosed inner end of the trough supports the cloth at about an inch and ahalf from the selvage, and operates in no respect to fold or roll thecloth in manner as stated. Therefore I lay no claim to any wheel templeor conical wheel temple as generally constructed, but in the well knowncylindrical roller or toothed cylinder temple.

I claim- Making the temple trough with a closed inner end, or a bar oranalogous contrivanc'e extending across the temple, and with respect tothe inner end of the cylindrical roller, and the upper edges of thesides of the trough substantially in manner and for the purpose hereinbefore set forth.

In testimony whereof I have hereunto set my signature.
